They are.
 
Certainly not the best of looking devices, especially if one wants to ceiling mount them.

Yes, they can keep the same SSID's, they will know how to do that, but you'll want to reinforce that to them.  Why do you want the Unifi network?  If your dealer wants to put in a different network, my point is "let them".  They have to support it.  And maybe another dealer can chime in, but I think an Araknis/Eero rooter to tooter network is supported directly by Control4 tech, which gives you an extra layer of comfort knowing they can support you via any Control4 dealer, regardless of what dealer put it in.

In no way is this a knock on Unifi, but for just a home AV network you won't experience any appreciable difference over the others.  If you came here telling us that you love Unifi protect cameras, etc... they I would say 100% Unifi is the way to go.  A ton of dealer/techs (and most of my buddies) use Unifi in their own projects because they like the "at a glance" look at the network and the Unifi camera app is crazy nice over others right now.  But - my buddies are tech guys that understand networking.  If you want a network to run your home automation system and be able to connect your phone and devices to wifi, go with your Dealer's recommendation.  

Best of luck!  You are asking good questions.

I mean, "yes."  But in the same way that a lay person can change the brake pads on their car.  It's a simple job if you've done it before and generally known what you're doing.  But could be dangerous.  Only you can evaluate this.

C4 is a dealer-supported model.  In general, you should turn over the whole thing to one person / company to avoid finger pointing and wasted hours diagnosing a system glitch.   You want "one throat to choke," even though you pay a premium for that peace of mind.   

I went with UniFi and did do most of the setup myself, but I have "eyes open" that my screw-ups could cause problems and I am on the hook to fix it.  But I also am comfortable changing out my own brake pads in th paddock during track days, and then blasting around at 140MPH 10 mins later on track... YMMV

A few points
Microcenter is great, but I'd suggest purchasing directly from Ubiquiti. Ubiquiti forces users to go through the retailer for warranty service. You most likely want the UDM-SE. The marginal price difference vs. UDM-Pro is not worth worrying about. If nothing else it has 2.5Gb WAN, which should be a minimum spec by now. If you are expecting to take advantage of high capacity of newer Wifi 6E and later (most people won't) you'll need an Enterprise switch with 2.5Gb ports. Ubiquiti uses 2 chipset manufacturers for their WiFi access points, MicroTek and Qualcomm. Some say mixing the 2 brands can cause issues. Qualcomm chipsets are newer and better supported by the chipset manufacturer. The ceiling APs with Qualcomm chipsets are U6-Pro and U6-Enterprise. The company seems to be on a better track with reliability of firmware. It's not hard to get the system working reliably. But it is also not hard to get it to be unstable if you make a configuration mistake. McCann Tech has a lot of info on Ubiquiti equipment: https://evanmccann.net

@msgreenf @CTMatthew  I purchased a 9,000 SF home recently that had an existing & extensive Ubiquiti Network and Ubiquiti Camera system in place (15-16 total cameras).  It says "Dream Machine Pro" when I log into the Protect App to see the cameras, if that matters.  We are now converting the home to Control 4, can you tell me if the Ubiquiti cameras can be ported into C4?  My other house has LUMA, and it works great with C4, I hope Ubiquiti cameras do too.   

Halo is the new line of C4 remotes.  Halo with hard buttons (and small screen) and Halo Touch (larger touch control screen, fewer hard buttons, more $$$)

This is obviously you typical BS personal opinion since you can literally see their equipment being used in countless locations. The stuff must be constantly sold out because everyone hates it.. 

I can't name one commercial customer of mine or other integrators I know, that is using UI products for their networks.  Any IT team that is worth a grain of salt would ditch them to the trash bin asap.
Meraki would be as close to a closed system like UI that I've seen in the field.  But that's because the company turned a warehouse stock manager into the IT Manager.  Cisco support basically sets it all up for him.

Control4 has had “not supported” list of networking equipment since pretty much forever. A lot of that is because it’s really difficult to have support staff aware of every product line, UI config etc… but also because of how the original structure of how c4 stuff works on the network, certain advanced networking features can stop system functionality. Specific to C4 mostly.  Halo seems to have something wrong in its programming that causes issues with Unifi.  Just like I dont blame ATT for C4s intercom woes when 2N doorstations work just fine independently or with other integrations. 

I have several unifi setups.   Including at my house.   After living with my own setup for several years now, it wouldn't be my personal choice anymore.  Unifi is pretty, but has a lot of issues.
 
1) things drop off of wifi for no reason.  Like pump controllers, the Halo remotes, a variety of other iot devices.   This is way more common on my unifi APs than on just about any other network gear I've used
2) it's damn frustrating.  They change the UI all the time for no reason.   There are options on the "legacy" interface they never bothered to put on the new interface. They move basic options all over the place every few months.
3) a lot of the basic features don't work correctly. For several months, the client reporting didn't work at all.  You would type it an IP address, that unify had clearly given a DHCP address to, and should know about, and it wouldn't show up as a device in the network.  The network topology map looks pretty, but often is just simply wrong.  Spanning tree doesn't seem to work at all sometimes.
4) they release half baked updates. The dream machine was a nightmare for the first two years, with basic features that didn't work at all.  Like DHCP....
 
There are a lot of other things too that just bother me. My point here is that it looks really really nice, but is not exactly reliable.  This is based on a lot of installs.....

I would NOT count on UI to solve your WiFi problems. Like others we have strange unexplained/insolvable dropouts and slowdowns and too many new bugs introduced with firmware updates that can take months to resolve. And there's no bug tracker so avoiding really bad updates can be difficult.
In the Edge days they were pretty rock solid, that disappeared w/ the UDM world of today. Of the options out there I think UI is one of or the best value but there are a lot of issues that come with those cost savings.  If someone else came along with the UI capabilities but more stability/reliability for 20-50% higher cost I'd be all over it (or same cost but an annual maintenance fee of 5% of the purchase cost or …). 
Definitely keep your Security Spy system. Discreet devices for discreet functions makes for a more robust/reliable system and makes troubleshooting much easier.
 

We had hundreds of Ubiquiti networks out there including my own house. The management interface is really cool. You can monitor everything. It is inexpensive. (really like those LV box size wifi6 ap's)
Once we started installing the Halo's we saw a lot of problems with network drop off. Over the prior years we had trouble with Araknis network equipment. But the latest Araknis is really good. We are seeing trouble free Araknis networks that are more reliable with higher speed tests than Ubiquiti. 
My own home we switched to Araknis Router, switches and AP's 3 months ago and not even 1 family member complaint since the changeover. In the 3 months not 1 halo and now halo touch drop off. Super responsive and reliable
 
 

Again, a lot of talks about individual experiences with Ubiquiti performance. C4 stability concern aside there is a reason why it is so heavily used by networking AV guys and standard IT pros, a lot of times in commercial spaces when stability and performance are even more important.  That hasn’t changed, it’s only grown. 

Your right. 
but having everything in unify space is so nice.  

The old 500's are so - so at best though.
With full support from Snap/Control4 - this would be my thought as well for this situation.
And yes if the switch has burnt out ports, it should probably be replaced, but I'd want to figure out WHY first (can't say I've seen this on araknis 210's at all)

If you don't personally have an enthusiasm for Ubiquiti and are just looking to get a better WiFi experience, your dealer would also be able to provide Access Networks' Ruckus bases APs. Those are fabulous APs and can run without a controller for most deployments. They're "in the family" and would allow you to keep your Araknis gear in place.

There are guys here that use Araknis APs regularly and could possibly solve your issues if you dont want to spend more. WiFi is also entirely environment based,  it’s possible your dealer doesnt have the proper skills to set up or diagnose interferences. 

Eero is designed for dummies. And as such when you need it to do something some engineer decided no one needs, then you're stuck and have to rip it out.
It's all good until it bites you, and in many projects it may behave, or it could be when you get a new widget and find it just wont work on their platform, or suddenly start having issues you never had after an update.
Dealers once bitten, don't go back.
Replace your APs. Ubiquiti or Ruckus Unleashed.
If you don't want to be your own system admin with Ubiquiti, maybe it's time your dealer takes a serious look at Ruckus.

Ditto.  I really like SecuritySpy.  My comments about not being a fan of Ubiquiti NVR were in reference to SS versus Ubiquiti.  Although this was a couple of years ago that I tried it, so maybe it's a lot better now.   The Apple Silicon Macs with HW Codec acceleration can deal with A LOT of cameras at 4K without complaining.   I don't know how much juice the Dream Machines have in that regard, so you might want to confirm that your cameras (at resolution / settings / features you want) won't put too much strain on the Dream Machine.   One thing that would be hard for me to give up is the AppleTV client for SS.  I use this often.
As I have noted elsewhere, I use the SS Homekit integration to throw alerts (e.g., if a vehicle (but not other motion) appears on driveway, flip a switch in Homekit).  Then I use a C4/Homekit driver to pick up that alert on the Homekit side and I fire off an "open gate" command.  Not sure how this would work with UniFi. 

They are a distributor. They own Araknis, Pakedge and Access. 

I'm very pro-Ubiquiti. It's really the only networking gear I'd use in a residential deployment, but I'm also curious why you'd want to pull apart what's basically a current Araknis system. I agree the APs could probably stand replacement if they've given you some problems, but otherwise you've got a pretty good system in place. Don't get me wrong I think Ubiquiti is easier in the long run, but your costs are sunk at this point!

Agreed...they have some beefy budgets these days at a good cost. Plus there really shouldn't be too much requiring that much power anymore. PoE has gotten quite a bit more efficient in last 5 years.
 
Likely is suggesting since besides Araknis and Pakedge it is one of the only other brands of networking gear for him to get from Snap.

It's just a janky product. I know that's not technical, but it's a good description of how we'd describe them after years of second, third, and fourth chances. They just have too many problems, and unlike enterprise systems have very little recourse to fix them. 

Ubiquiti has enterprise networking capabilities pretty much across the board… at a price noticeably better than most. 
Eero is consumer grade networking equipment with an intuitive and setup friendly app and mostly plug and play components. It will have some limitations from an advanced network perspective and can be problematic with certain advanced C4 features but in most cases  it works just fine. 
Araknis is an AV networking brand. They fall in the middle providing more pro/enterprise style gear with simple UIs, performance stats and features. Their newer equipment finally has some more powerful hardware and basic things like firewall rules we expect on expensive routers. Ovrc management and Snap service is definitely its biggest strength.
 
A USW-Pro-24-POE (400W) is 1/3rd the cost of a Araknis 310 Series 24port. It’s L3 and has 25 more watts. 
 

One thing about UniFi switches is they have lower PoE budgets than Araknis so be mindful if you have a lot of PoE needs outside of the UniFi system itself. They're usually adequate for their own APs and some cameras, but it could mean the difference in choosing between the regular switch and the pro version (where there's no 16 port available).
The Dream Machine Pro is beyond adequate for home use and if you're at all savvy you'll be able to appreciate the "single pane of glass" view of your network. I'm able to get to the bottom of network issues very quickly because I don't have to log in and out of half a dozen boxes to figure out what's going on.
